AC roof unit doesn't work

HI All,

I have 2 AC roof units. Back one works fine. Front one will blow air on hi and low when I turn it on. When I turn it to auto and then cool, the thermostat clicks and the unit buzzes like it's trying to get going but does nothing. I opened it up and fan turns fine manually. I try to help it get going while it's buzzing, but nothing. There are 3 capacitors. I am thinking the problem is one of those. Thoughts?

Change them out with a hard start kit, as it's sometimes called and the compressors start capacitor is the most likely culprit. What ever you have left over, with buying them all, keep for a spare.
I changed one out on the road last year and found it at a trailer sales dealer, but if no hurry, Amazon should have what you need. Again, no problem if it doesn't work, as it's nice having a spare on board and it's not like they're overly expensive.
